I just got the nad hp50 and quite like this headphone. I want to buy a new small dac with headphoneout/lineout to use with these headphones and my speakers and my laptop or ios device as source.
I was thinking of the meridian explorer v2 but its output impedance is 5 ohm which i think is a bit high.
Also it seems to need an active usbhub to work with ios devices.
I thought for ios use you needed a device with an apple certified chip but that seems to have changed with ios 7?
Are there any other recommendations in small dacs around 300 euros that work with ios?
